FEED-GAGE FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 511,154, dated December19, 1893.

Application filed January 31, 1893- Serial No. 460,311. (No model.)

T0 at whom it may concern..-

Be it known that I, EDWARD L. MEGILL, a citizen ofthe United States,residing in Brook lyn, Kings county, New York, have invented certain newand useful Improvements in Feed-Gages for Printing-Presses, of which thefollowing is a specification.

My invention relates to an adjustable gage adapted to be applied to theplaten of a printing press, or for general use in registering sheets inprinting.

The invention will be fully described hereinafter with reference to theaccompanying drawings, and its novel features will be carefully definedin the claims.

In the said drawings, which illustrate an embodiment of theinvention-Figure l is a perspective view of the gage, detached. Fig. 2is a plan of the same. Fig. 3 is an under side view of the same. Fig. 4:is a vertical, longi tudinal section showingthe gage set on the platen.Figs. 5 and 6 illustrate slight modifications which will be hereinafterdescribed.

My gage will be made, by preference, of sheet steel, and consists, asherein shown, of three pieces, namely, the body, the clamping lever, andthe stripper. The body comprises a base-plate a, a pin 1), and agage-head, 0. These are integral and are formed by bends in the sheet ofmetal. The pin 1) is joined to the base-plate a, at the rear end of thelatter and extends forward under said plate, its front, free end beingpointed, as shown. The gage-head c is formed on the front end of thebase-plate by bending the sheet metal as clearly shown. The parts are soproportioned that'the point of the pin 11 projects forward a littlebeyond the face of the gage-head, and

the latter has a shallow recess, cl, formed in its lower edge at thepoint where the pin passes under it.

The base-plate a and the pin 1) form the jaws of a clamp, which tend toopen slightly by the spring of the parts, and which may be broughttogether by means of an angular clamping lever, e, which is fulcrumed inturned up lugs, g, on the pin 1), and situated over the base-plate a,whereby, when the longer arm of the lever is pressed down, the shorterarm thereof will bear on the plate a, thus bringing the jaws of theclamp forcibly together. In Fig. 1 the lever e, is represented as thrownup and the clamp open. When the gage is to be set in the platen sheet,00, the point of the pin 1) is inserted therein and pushed forward asfar as desired, when the lever e is pressed down, thereby closing thejaws of the clamp on the part of the sheet 00 between them. This is theposition of the parts seen in Fig. 4. The pressure of the gagehead onthe sheet at each side of the point of the pin, and the clamping of thesheet between the base-plate and the pin, serve to hold the gage firmlyon the platen sheet.

The gage may be shifted in position within limits, after being once set,by throwing up the long arm of the clamping leverand moving the gageforward or back and then again depressing the lever as before.

The stripper, t, is a thin strip of metal, mounted adjustably in thegage so that it may be made to project more or less from the gage-headc. In the uprightfront plate of the latter is an aperture through whichthe stripper passes, and in the part 0 of the head, back of the saidfront plate and connecting the latter with the base-plate a, is anaperture formed by punching a part of the metal to form a spring finger,j, which presses elastically on the stripper and holds it in place,after adjustment, with sufficient firmness for all practical purposes.The stripper is not pressed upon by the lever e, as a notch is formed inthe shorter arm of the same to permit the free passage of the stripperunder it.

The above description of the spring finger 9' refers to the constructionseen in Fig.4; but this finger may be formed in other ways, two examplesof which are seen in Figs.5 and 6.

InFig. 5 the spring finger is represented with its free end directedforward and pressing upward, while in the construction of Fig. 4., thesecharacteristics are reversed.

In Fig. 6, the spring finger is formed by punching back a part of theupright plate of the gage-head.

As represented herein and clearly shown in Fig. t, the plate a andpin 1) are formed intogral, being joined at the bend in the metal plateor sheet; but they may as well be nonintegral and be secured together atthis point by any of the well known modes of securing together two metalplates, as by a rivet, for

example. The lugs 9 rise from the pin well toward its rear end andextend forward to the fulcrum point of the lever, as seen in Fig. 1, inorder that the pin may be inserted to a considerable extent under theplaten paper and also so as to place the point where the clamping leverimpinges on the base-plate, well forward toward the gage-head. This willinsure a better clamping efiect than it the lever were fulcrumed at apoint nearer to the point where the plates are united.

The advantages of a clamping lever over a wing nut and screw for thepurpose herein set forth will be obvious to one skilled in the use ofthese gages. The rotary. twisting motion in setting the nut is liable todisplace the gage on the platen, and the pressure from the screw willvary according to the power applied by the user. With the lever there isno twisting of the gage and the pressure is always the same.Moreover,there is no liability to accidental loosening of the clamp whena lever is employed.

vHaving thus described my invention, I claim- 1. A feed-gage comprisingas its essentials, a base-plate provided with a gage-head, a pin underthe base-plate and connected therewith at its rear end, the free end ofsaid pin being situated under the gage-head, and a clamping leverarranged over the base-plate and fulcrumed in upwardly projecting lugson the pin.

2. A feed-gage comprisingabase-plateprovided with a gagehead, a pinunder the baseplate and connected therewith at its rear end, the freeend of the pin projecting forward be yond the upright part of thegage-head and coincident with a recesstherein, and aclampin; leverarranged over the base-plate near the gage-head, the lever beingfulcrumed in lugsg, on the sides of the pin, said lugs being joined tothe pin at points back of said fulcrum, substantially as and for thepurpose set forth.

3. In a feed-gage, the combination with an adjustable base-plate havinga securing pin and agage-head mounted non-adjustably on said base-plate,said gage-head being furnished with apertures for the passage of astripper and with a spring-finger at one of said apertures, of the saidstripper, clamped elastically between said spring-finger and the rearpart of the gage-head.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

EDWARD L. MEGILL.
